Text For Citation: 01 Item/Group: 016 Hazard:

29 CFR 1910.272(j)(3): Compressed air was used to blow dust from ledges, walls, and other areas in grain handling facilities when machinery presenting an ignition source was not shut down, and/or when all other known potential ignition sources in the area had not been removed or controlled: The employer is failing to protect employees from explosion hazards associated with employees using compressed air to blow potentially combustible dust accumulations off horizontal surfaces throughout the facility without de-energizing all potential ignition sources. The most recent occurrence of this was found at the facility located at 501 Division Ave, York, NE 68467 where the employer has employees using compressed air to blow down the residual dust build up off of the upper horizontal surfaces without securing all energy sources and the sewing and bagging line that has been improperly wired and does not meet Class II Division 2 dustproof requirements of NFPA 70. Instances of potential ignition sources include but are not limited to: i. The 110v electrical box mounted on the back side of the bagging line is not designed as dust proof and currently the broken door does not secure leaving exposed live wiring. ii. The 460v electrical box mounted on the back side of the Fischbein sewing machine is not designed as dust proof. iii. The overhead fluorescent lights along the bagging/sewing line are not designed as dust proof. iv. The plug connection between the flexible cord brining power to the flexible cord for the 460v box located on the back side of the sewing machine is not designed as dust proof. v. The portable power tap located on the back side wall behind the bagging/sewing line is not designed as dust proof along with the pallet wrapper/scale printer and monitor that are plugged into the PPT. vi. The light switches located on the wall directly behind the bagging/sewing line are not designed as dust proof.
